Yes I do, I really like traveling by bus. First, it is very convenient because I don't have to psend much fuel or electricity to go to far-away places. (câu "good for the environment" nó kh hợp lý lắm vì xe bus nó vẫn thải ra khí độc). Second, traveling by bus is cheap, so I can save my money. Also it is very safe and comfortable. I don't have to drive by myself and I can relax, talk to my friend and listen to music. In conclusion, traveling by bus is a good choice. (Finally dùng để thêm ý, In conclusion để kết luận. Cái này e đang kết luận nên ph dùng "In conclusion")

Your breath

\(\rarr\)

The answer is "breath" or "air." Even the strongest person cannot hold their breath for more than a few minutes.

Câu trả lời là "hơi thở" hoặc "không khí." Ngay cả người mạnh nhất cũng không thể giữ hơi thở của mình quá vài phút.

Bài 1: Thực hiện các phép nhân sau:

a) 3x^2 * (5x^2 - 7x + 4) = 15x^4 - 21x^3 + 12x^2

b) (2x^2 - 5x) * (3x^2 - 2x + 1) = 6x^4 - 4x^3 + 2x^2 - 15x^3 + 10x^2 - 5x = 6x^4 - 19x^3 + 12x^2 - 5x

c) (x^2 - 8x + 1) * (-2x^3) = -2x^5 + 16x^4 - 2x^3

d) (4x^2 + 2x + 1) * (2x - 1) = 8x^3 - 4x^2 + 4x^2 - 2x + 2x - 1 = 8x^3 - 1

e) (3x^5 - 9x^6 + 12x^9) : (3x) = x^4 - 3x^5 + 4x^8

f) (3x^5 - 9x^6 + 12x^9) : (-3x) = -x^4 + 3x^5 - 4x^8

Bài 2: Thực hiện các phép chia sau:

a) (6x^3 - 7x^2 - x + 2) : (2x + 1) = 3x^2 - 5x + 2

b) (2x^4 - 10x^3 - x^2 + 15x - 3) : (2x^2 - 3) = x^2 - 5x + 1

c) (x^3 - 7x + 3 - x^2) : (x - 3) = x^2 + 2x - 1

d) (2x^4 - 3x^3 - 3x^2 - 2 + 6x) : (x^2 - 2) = 2x^2 - 3x + 1

e) (9x^4 - 6x^3 + 15x^2 + 2x - 1) : (3x^2 - 2x + 5) = 3x^2 - 1 (Câu này chia hơi lẻ, đại ca kiểm tra lại đề xem có nhầm số nào không nhé).

f) (9x^5 - 6x^3 + 18x^2 - 35x - 42) : (3x^2 - 7) = 3x^3 + 5x + 6

a) Thu gọn và sắp xếp các hạng tử của mỗi đa thức trên theo lũy thừa giảm dần của biến.

A(x) = (5x^3) + (-4x^2 - 7x^2) - 2x + (-8 + 1) = 5x^3 - 11x^2 - 2x - 7

B(x) = (-3x^3 - 2x^3) + 4x^2 + (x - 2x) + 9 = -5x^3 + 4x^2 - x + 9

b) Tìm đa thức N(x), biết N(x) = A(x) - B(x).

N(x) = A(x) - B(x) = (5x^3 - 11x^2 - 2x - 7) - (-5x^3 + 4x^2 - x + 9) = 10x^3 - 15x^2 - x - 16
